Edward Angle: E arch, pin and tube, ribbon, and edgewise. The E-arch was only capable of tipping teeth to a new position. With the pin and tube, tooth movement was accomplished by repositioning the individual pins at each appointment.

The edgewise was created to overcome the deficiencies of the ribbon arch.
